jq: Creating string out of JSON containing optional fields and conditionals


jq: Creating string out of JSON containing optional fields and conditionals

wish of those help Optional fields can be handled using an if-then-else statement. And you don't need to_entries here, just keep keys in a variable.
code :
$ jq -r 'keys_unsorted[] as $k | .[$k].files[] | .type + "/" + $k +
if has("name") then "." + .name else "" end' file.json
static/main.ca.crt
dynamic/main.key
dynamic/main.crt
static/ota.ca.crt
static/ota.sig.pub
dynamic/random

may help you . I would like to create a JSON string using multiple input fiels with same cla. Allow me to show you my HTML for explanation
code :
var inputs = $('input.email'), tmp;
$.each(inputs, function(i, obj) {
  tmp = {
    'title': $(obj).attr('title'),
    'email': $(obj).val(),
    'name' : $(obj).siblings('.name').val()
  };

  ServerUser.push(tmp);
});

it should still fix some issue This seems to be a known issue with Generics-based parsing. Aeson has had the same issue and the maintainers have decided to deprecate that functionality in favor of a Template Haskell-based strategy: https://github.com/bos/aeson/issues/118
With Aeson, your code would look very similar:
code :
import Data.Aeson
import Data.Aeson.TH

data Record = Record {
    myMandatoryField :: Integer,
    myOptionalField :: Maybe Integer
} deriving (Eq, Show)

$(deriveJSON id ''Record)
$ ghci
λ :l Main.hs
Ok, modules loaded: Main.
λ encode $ Record 5 Nothing
"{\"myOptionalField\":null,\"myMandatoryField\":5}"
λ decode it :: Maybe Record
Just (Record {myMandatoryField = 5, myOptionalField = Nothing})
instance FromJSON Record where
    parseJSON = withObject "record" $ \o -> Record
        <$> o .: "myMandatoryField"
        <*> o .:? "myOptionalField"

instance ToJSON Record where
    toJSON (Record manf optf) = object $ catMaybes
        [ ("myMandatoryField" .=) <$> pure manf
        , ("myOptionalField" .=) <$> optf ]
Avoid even Option fields. Always empty string for String and 0 for Int optional fields

will help you I think you would regret avoiding Option because of the loss of type safety. If you go passing around potentially null object references, everyone who touches them has to remember to check for null because there is nothing that forces them to do so. Failure to remember is a NullPointerException waiting to happen. The use of Option forces code to deal with the possibility that there is no value to work with; forgetting to do so will cause a compilation error:
code :
case class Foo(name: Option[String])
...
if (foo1.name startsWith "/")  // ERROR: no startsWith on Option
trait FooJsonProtocol extends DefaultJsonProtocol with NullOptions {
  // your jsonFormats
}

hop of those help? I am learning Go right now and would like to initialize a type using variadic arguments without using reflection. Is it possible? , It's possible with a little bit of code:
code :
func CreateMyType(arguments ...string) *MyType {
    var m MyType
    switch len(arguments) {
    case 3:
        m.field3 = arguments[2]
        fallthrough
    case 2:
        m.field2 = arguments[1]
        fallthrough
    case 1:
        m.field1 = arguments[0]
    }
    return &m
}

this one helps. So you need to have the SecondaryAlies in another if/else condition like the below:
code :
If($SecondaryAlias)
{
    New-SPSite -Url $siteUrl -name $sitename  -Language $SiteLanguage -Template $SiteTemplate -OwnerAlias $SiteOwner -SecondaryOwnerAlias $SecondaryAlias
}
else
{
    New-SPSite -Url $siteUrl -name $sitename  -Language $SiteLanguage -Template $SiteTemplate -OwnerAlias $SiteOwner
}
